Steering wheel shaking with rack and pinion?

makesure rack and pinion frame anchoring bolts are tight if they are the least bit loose it could translate the vibrations to the steering wheel check the rack securing frame bolts or inner tie rod ends for a loose clicking sound by putting car up in the air on jack stands and grabing tire on left and right side and pulling and pushing looking for loose clicking sound if you hear it have another person observe the inner tie rod as you push and pull on the tire to verify sound and location. PS ,outer tie rod ends could be suspect so also look there when pushing and pulling on tire
